Abstract [en]

The study aim to examine how Sweden's existing housing stock needs to adapt to achieve the objectives and agreements signed to counteract climate change as well as, what specific measures should be prioritized in order to achieve the objectives within the set timeframe. To answer the purpose, the study has used theoretical and real objects where extensive energy savings have been performed. This potential has been applied to the entire housing stock and its environmental impact has been calculated.The study focused on the category of single-family homes and apartment buildings. The results showed that when all renovation measures were applied, greenhouse gas emissions fell by 88% from 1990 years, energy efficiency increased by 47% from 2016 years, and the share of renewable energy was considered to continue to increase. The proportion of fossil fuels was relatively large 1990 for heating homes and hot water that were phased out to more environmentally friendly alternatives over time. This meant that 2016 was the housing stock were significantly below the targets set for greenhouse gas emissions for years 2020 and 2030 i.e. The targets were already fulfilled in 2016. However, the target for 2050 was set at a reduction of at least 80%, which meant that all the measures for reducing energy consumption in the study needed to be used to reduce greenhouse gas emissions to set targets.The study shows that all the goals that Sweden has adopted can be achieved or achieve great improvement as all of the study's energy saving and carbon reduction proposals are implemented.
